So i curently bought a Optoma hd71 for a home theater system. So i went out and bought a sony sound bar with Hdmi's hook ups so i connect the projector with hdmi. Once i turned the system on it started to flash a green screen and then back to the regualer screen every other second. So i thought its my sound bar thats doing all this so i connected my lg dvd player with no sound directly to the projector and the projector works!!!!! I also used the same hdmi cables! and set both the lg dvd player and the sound bar to 720p! So i went out and bought another sound system this time a LG sound system so i connected the sound system with all the same hdmi cables. I turned it on and now the screen color is all f$$$ed up. So i set the sound system up to 720 p the pictures is like a rainbow its really though to make out anything. Whats wierd is my LG dvd player will work connected directly with the projector but once i go through the sound systems the picture gets messed up......CAN ANYONE HELP Me with this issue?? Has anyone else have this happen to them? If so can u guide me in the right direction before i throw my projector out the window and scrap this project?

Hello, I have been looking at Optoma Hd71, I found one new on clearance for under $700 with tax. My question is,would this be a deal I shouldn't pass up or just a average deal for this projector. Thanks,

I need the experts’ suggestions to help me eliminate these headaches whenever I use my home theater. I have a 106” Matte White 1.0 gain screen with an Optoma HD71 2400 lumen projector, which is calibrated using Projectorreviews.com recommended settings, and puts out an actual 1040 – 1100 lumens. My eyes are 14’ away from the screen when seated at a height of 40”, my basement HT has no windows with blue walls and standard white drop ceiling, and the bottom of the viewable image edge is 30” off the floor. Is my problem: • the screen is mounted too high; • the projector is too bright; • I am seated too close to the screen; • Something else? Anyone with experience in such matters, please respond. I am a bit puzzled because I have used my brother’s HT for years without this problem. He has a 106” grey screen and a significantly dimmer projector but his seating is only 3” further back at the same height and his image bottom is 3.5” higher than mine. Admittedly, I do wear sunglasses almost all the time outside because I do not care for bright light. Thanks.
